f := piecewise( is(floor(x)::odd), 1, 0 ): seq( f(n), n=-5..5 ); plot( f, -5..5 ); produces (Maple 11) the expected output (sequence alternates 1 and 0 - plot is a square wave). Replace the definition of f by f := piecewise( floor(x)::odd, 1, 0 ): and the seq command still operates as expected but the plot shows f=1 between 1 and 2 but otherwise 0. Does anybody know what is going on here? It's probably not important but I am confused. Toby
